+This signal is sent out to include tab links on the detail page of an organizer.
+Receivers are expected to return a list of dictionaries. The dictionaries
+should contain at least the keys ``label`` and ``url``. You should also return
+an ``active`` key with a boolean set to ``True``, when this item should be marked
+as active.
+
+If your linked view should stay in the tab-like context of this page, we recommend
+that you use ``pretix.control.views.organizer.OrganizerDetailViewMixin`` for your view
+and your tempalte inherits from ``pretixcontrol/organizers/base.html``.
